Central Election Commission Vladimir Churov said that with 100 percent of precincts counted, Medvedev won Sunday's presidential election with 70.28 percent of the vote. The turnout was 69.78 percent.

Communist Party chief Gennady Zyuganov trailed with 17.72 percent, while ultranationalist Vladimir Zhirinovsky followed with 9.34 percent and a little-known Andrei Bogdanov captured 1.29 percent, Churov said.

Final official results will be released later this week.

Medvedev's election was assured by support from President Vladimir Putin and the Kremlin's tight control over the national media and political landscape.

Across Russia, voters said they were pushed, cajoled and pressured to cast ballots as part of a Kremlin campaign to ensure a strong victory for Putin's protege.
